Ive used this in three different setups. One at the end of the cage, using just one ramp for a piggy who had to see everything, both of the other times its helped shy piggies see without being seen. Two caveats. Poop will fall off the side, there isnt any coroplast on the top edge, but its not the end of the world. Second, this works best in a XL/Jumbo cage or a L cage that is one level, in my experience.
